FONTANA, Calif. — Joey Logano simply got mad after Greg Biffle put Logano in the wall yesterday in the NASCAR Nationwide Series race at Auto Club Speedway.

His father, Tom, tried to get even, and lost his NASCAR credentials in the process.

Logano recovered to win the 300-mile race, pulling away from Brian Vickers over the final two laps to pick up his fifth series win of the year, and second in a row.

Yet while the 19-year-old exalted in Victory Lane, his father was being taken to the NASCAR hauler to talk with Nationwide Series director Joe Balash after a postrace confrontation with Biffle.

The elder Logano approached Biffle's car in pit lane after the race and made at least one hand gesture in Biffle's direction before a NASCAR official intervened.

"A NASCAR official pulled Mr. Logano's annual credential after he confronted the 16 on pit road," NASCAR spokesman Ramsey Poston said.

Tom Logano will be eligible to sign for a single-event license while officials review the event and can attend today's Sprint Cup event at the track, Poston said.

Tom Logano was apparently upset about the scrape Biffle and his son got into on lap 50. The veteran was challenging for the lead when he hinted over the radio that he was going to put the young driver in the fence.

Moments later Biffle slid up the track while passing Logano on the inside, a move that slightly damaged Logano's No. 20 Toyota. Dave Rogers, Logano's crew chief, called Biffle "a coward" over the radio.

Poston said NASCAR is reviewing the video. Joe Gibbs Racing president J.D. Gibbs had no comment and neither Logano could be reached for comment following the race.

Logano benefited from a late-race collision between Hamlin and Biffle, then caught another break when a late caution led to a green/white/checkered finish. He dominated the restart, pulling away from Vickers for the victory.

"I was going to try to salvage a top 10 out of it and all of a sudden I'm sitting third and all of a sudden I took the lead and I thought, 'I got a shot at this thing,' " Logano said. "I can't believe it."

INDY RACING LEAGUE

FRANCHITTI TRIUMPHS

Dario Franchitti emerged victorious from one of the closest points races in series history yesterday, winning the season-ending Indy 300 at Homestead-Miami Speedway in Florida in the first caution-free IRL race ever.

He used a significantly different fuel strategy than the other two title contenders, Scott Dixon and Ryan Briscoe, and was rewarded with his second championship in three years.

"I still can't believe it," said Franchitti, the scent of champagne obvious on his soaked racesuit an hour after the checkered flag came out in his honor. "Really, I can't."

Franchitti sat back in third place, about 25 seconds behind Dixon and Briscoe, saving fuel over much of the final 50 laps. When his two fellow contenders pitted late, the title was his.
